ContaminationSensor Module Comfort CSM-CPortable plug-and-work module to measure solid contamination and water saturation (optional) in hydraulic and lubrication fluids containing a high proportion of air bubbles. For temporary or permanent installation.
HYDACLab® Oil condition sensor
Electronic clogging indicator type GW
MetallicContaminationSensor MCS 1000 Series
We take care of:Condition monitoring of oil cleanliness and oil ageing in hydraulic and lubrication oils
Electronic measurement of pressure, temperature, position and flow rate
Cooling and filter systems for wind turbines
Measures to extend service life and optimize operational safety through high-quality filtration systems
Hydraulic systems and components for safety and yaw brakes
Pitch control
In-plant technology: Test rigs / test room equipment for gearbox, rotor bearing, cylinders, accumulators ...
Secure and gentle mounting of cables
Fluid Condition Monitoring
Sensors for permanent measurement of oil cleanliness class, wear particles, water saturation level and oil ageing in hydraulic systems. By monitoring the gearbox and bearing lubrication, wear and tear can be detected at an early stage and damage can be avoided.
HYDAC Measuring Technology
HYDAC offers sensors for measuringPressureTemperaturePositionFlowFilter contamination andFluid level.
Gearbox cooling: Motor pump unit with filtration
Gearbox / Generator cooling: Flow rate: < 350 l/min Pressure: < 16 bar dynamic Medium: Oil or water / glycol
Integrated pressure and thermally-controlled bypass valve on the cooler
Generator / inverter cooling: Water-glycol circuit
Filtration for hydraulic and lubrication oils
OffLine Filter Pressure OLFP Compact offline filter with high pressure stability
Filter block solution
Breather Dryer BDE
Optimized filter elements (e.g. BN4HX) also with Quality Protection to protect against product piracy
Trimicron elementsOffline filter elements for combined removal of oil ageing products, water and solid particles (suitable for OLFP offline filters)

Gear oil is cooled using plate heat exchanger, which is supplied with a water / glycol mixture also used to cool the generator. Heat is then dissipated via a heat exchanger.
Cooling system: Gearbox (oil / air cooler version)
